How to draw all three types, project the target, and handle the sweep
A triangle forms when one side of the market steps in earlier every rotation while the other side defends a single price. The flat side builds equal highs or equal lows, and equal highs or lows are where resting orders pool. This page shows how to draw all three types, project the measured move, and trade both resolutions: the clean breakout and the sweep.
An ascending triangle, fully played out. Three near-equal highs build a flat ceiling where resting orders pool, higher lows squeeze price into it, a strong candle closes through, and the retest holds the old ceiling as new support.

01 The Three Types
The three triangle types
One side defends a price while the other steps in earlier each rotation
Ascending, descending, symmetrical: all three form the same way. One side of the auction keeps stepping in earlier than it did last time while the other side defends a single price.
In an ascending triangle (the hero chart above), sellers defend one price again and again, so the highs come out equal. Buyers do not wait for the old low anymore; they buy sooner every dip, so the lows rise. Price gets squeezed into the ceiling.
A descending triangle is the mirror image: buyers defend a floor, highs sink as sellers get more aggressive, and price gets squeezed into the floor. A symmetrical triangle is both at once: lower highs and higher lows, neither side dominant yet, the range simply compressing until something gives.
Descending triangle. Equal lows build a flat floor while lower highs press into it. The floor is where the resting orders sit, and the breakdown runs through it.Symmetrical triangle. Both lines slope and neither side owns a level. It usually resolves in the direction of the trend that walked into it.

Read the flat side first
Flat highs mean sellers are organized at one price; flat lows mean buyers are. The sloped side shows which side is getting impatient. A defended level plus an impatient other side is the whole pattern.
!
The direction is not guaranteed
Textbooks say ascending triangles break up and descending triangles break down. Often true, never promised. The flat side holds a pool of orders, and that pool can be used for a real breakout or for a sweep. Chapter 5 covers how to tell them apart in real time.
02 Drawing The Lines
How to draw each type
Flat line first, wick anchors, two touches per line with a third as confirmation
Draw the flat side first: that is the level the market is organized around. If you have to bend the lines to see the triangle, there is no triangle.
Find the defended price. Two or more swing highs (or lows) that stop within a few ticks of the same price. Use the wicks, not the bodies; the wick is where the orders actually sat.
Draw the flat line through them. Horizontal, at the level the wicks keep tagging. If you need to tilt it more than a hair to connect the points, you are drawing a channel, not a triangle.
Connect the rising (or falling) side. Two higher lows for an ascending triangle, two lower highs for a descending one, anchored on wicks. Two touches define the line; a third touch confirms it.
Confirm the squeeze. Price should be making smaller rotations as it approaches the flat line. If the swings are not compressing, the two lines are a coincidence, not a pattern.
Draw order for an ascending triangle.Flat top first (the defended price), rising line second. Then wait for a candle to close beyond the level instead of buying the first poke.
✓
Equal highs mark both triangle ceilings and order pools
Mark every spot on your chart where two or more swing highs stopped at the same price. That list is every potential ascending-triangle ceiling and every buy-side order pool at once. The pattern and the pool are the same thing.
!
Upgrade the sloped line to a trend zone if the trend takes over
The sloped side of a triangle is a trend line: two touches define it, a third confirms it. If the pattern fails and price starts trending away, thicken that line into the AoT trend zone: line 1 through the shallow edges of two reactions, line 2 parallel through the deepest wicks of the same two reactions. The band absorbs the wicks that fake out a single line.
03 The Measured Move
Measuring the expected move
The pattern carries its own target: its height.
Triangles come with a built-in expectation. Take the height of the pattern at its widest point and project it from the breakout. That is the classic measured move.
Measure the height. Vertical distance from the flat line to the first swing on the sloped side (the widest part of the triangle).
Project it from the breakout price. Breakout at 100 with a height of 18 gives a measured target of 118 for an upside break (or 82 for a break down through a floor).
Treat it as a zone, not a pin. Scale out into it. If a higher-timeframe level sits just in front of the target, respect the level, not the textbook number.
The measured move. Pattern height (H) taken at the widest point, then the same H projected up from the breakout. Price tags the target zone and stalls; that is normal, take profit there.
i
The height works because enough traders act on it
The height of the triangle is the size of the last uncompressed rotation, a rough measure of how much fuel the coil stored. The projection holds because enough traders act on the same number to matter, which also means everyone else is watching it too.
!
A target is a magnet, not a promise
Measured moves fail exactly when everyone needs them not to. Do not hold a full position through pullbacks because "the target says 118". Take partials, trail the rest, and if price reclaims the flat line against you, the pattern is over regardless of the target.
04 The Order Pool
The flat side is a pool of resting orders
Stops and breakout entries stack at one advertised price
The flat side of a triangle is, by definition, a stack of equal highs or equal lows, and equal highs or lows are the most reliable place on any chart to find resting orders.
Think about who has orders just above an ascending triangle's flat top. Every trader who shorted the level has a stop-loss buy order a few ticks above it. Every breakout trader has a buy-stop entry order in the same place. Two different intentions, one price, one direction: buy. The pattern manufactures a dense pool of buy orders at an obvious level, and it advertises the location to everyone.
Institutions filling large positions need exactly that: size willing to trade at a known price. Price gets drawn into the pool because that is where big players can get filled. This is why triangles resolve violently in one of two ways: the pool fuels a real breakout, or the pool gets consumed in a sweep and price reverses. Quiet resolutions are the rare case.
The flat top as an execution desk sees it.A shelf of resting buy orders (shorts' stops plus breakout entries) sitting at one advertised price. The squeeze pulls price toward that fuel.
i
The more obvious the pattern, the bigger the pool
Patterns create areas of interest, and interest parks orders. A triangle that every trading account can see carries a bigger pool, so it resolves harder, in whichever direction the players filling size choose. Obviousness raises the stakes; it does not raise the reliability.
!
Keep both of your orders out of the pool
A buy-stop above the flat top with a stop-loss just back inside places both orders inside the pool that gets harvested. If the market sweeps the level first, you are entered at the worst price and stopped at the second-worst. Trade the break with the stop below structure, not one tick inside the triangle.
05 Breakout Or Sweep
Breakout or sweep: rules for both outcomes
Both feed on the same pool; the close of the candle tells you which one you got
A triangle resolves one of two ways: it runs clean through the level or it sweeps the level and reverses. Prepare a rule for each instead of predicting which one comes.
The failure mode. A wick sweeps the flat top, consumes the stops and breakout orders parked there, closes back inside, and the same fuel powers the reversal down through the rising line. Wick beyond, close inside: that is a sweep, not a breakout.
The handling rules
Trade closes, not pokes. A breakout is a full candle body closing beyond the flat line. A wick beyond the line that closes back inside is a sweep until proven otherwise.
Prefer the retest entry. Let the breakout happen without you, then buy the return to the flat line (the hero chart's "retest holds" moment). You risk missing runners; you skip nearly every fakeout. That trade-off pays for itself.
Put the stop below structure. Below the most recent higher low for an upside break, not one tick under the flat line where the crowd's stops sit.
Respect the reversal signal. If price sweeps the level and closes back inside, do not argue. The pattern's fuel is spent; the higher-probability trade is now the other direction, especially once the sloped line gives way.
✓
Write both trigger prices before the level breaks
Write down two prices in advance: where the breakout closes to confirm, and where a sweep closes back inside to invalidate. Decide both while you are neutral. When the candle prints, you execute a decision you already made instead of reacting to one the market made for you.
The Triangle Playbook
Identify the flat side. Equal highs or equal lows tell you which side is organized and where the liquidity pool sits.
Draw flat line first, sloped line second. Two wick touches define each line, a third confirms it, no forcing.
Measure the height at the widest point and project it from the breakout for a target zone.
Wait for the close beyond the level; a poke is not a breakout.
Enter on the retest when you can, with the stop below structure, not inside the pool.
Sweep and close back inside? The pattern failed; the better trade is usually the reverse.
